Hmm, well my top 10 (i.e. those things we almost always do) wouldn't be the same as those things I might recommend to a first-timer. For example, I think La Nouba is a great experience, but it wouldn't be on my list to do every trip (in fact, we've only seen it once). I'm not a huge fan of Fantasmic, but I think everyone should see it at least once. And
my 'essentials' list would probably change each time to include anything new. These days, I could happily visit Orlando and never visit a park - something I never thought I'd catch myself saying.
Mall at Millenia. We do quite a lot of shopping, but this is top of my list.
I love the whole experience - the mall is immaculate and there are some great restaurant options;
The Mummy. This is still my favourite coaster, despite having ridden Expedition Everest;
Expedition Everest;
Soarin';
Spiderman;
IllumiNations;
Carousel of Progress;
At least one meal at a top restaurant;
Drinks around the World - we like nothing better than strolling around World Showcase. Except strolling around WS during the International Food and Wine Festival, of course!
Shrek 4D;
Mickey's Philharmagic. Not as clever as Shrek, but there's just something about it. I always have a lump in my throat, particularly during the Lion King segment. You really do need to sit near the back for this one, though.
Interesting that many of those I've chosen are the newer attractions. Some of the older ones are probably equally as good, but I guess it's easy to become blase about it all. I'm thinking Terminator 2 (compared with Shrek, say) and R'n'R (compared with The Mummy). There are so many more things which we invariably do, that I think a 'top 30' list would be more realistic for most people.
